IMPROVEMENT m Bur-mess.

Teal! whom'tt concern.- I

Be it known that I, (Lemmy Conn, of Ithaca, Tompkins county, New York,have invented an Improved Hinge; and I do hereby declare'the followingis a full Figure 1 is a view-of my hinge. Figure 2 isapartially-sectional view, looking down uponit,and

Figure 3 is a view of the reversible halfor part of the hinge. I j

My object is to make a hinge in such a manner as to-fit either right orleit-hand doors, gates, &e. For this, the jamb-part' is made in such away as to fit eith'gr the right orlefirhand jamb of any door, and thedoor-part is so made that, by reversing it, or turn eitherto the rightor left hand. A third part of the hinge is. the ornament, that fitseither cavity in the' the door-part or half, which fit into a'corresponding cavities for the hinge-rod or axis do not connect, butleave a middle web between them.

' In the drawings,'in fig. 1

A is the part or half of the hinge that is fastenedto the jamb ofthedoor, with the screw-holes counterhin'ge, projeoted'beyond theperpendicular line E, so

B is the doorpart or'half of the hinge, with-the screw holelscountersunk in the common way, but its horizontal (red) lines E and Eare so made as to fit the top line of the jamb-part'A, be either endplaced upward.

Two hinge-cavities are made in the rounded hinge used cavity of thehinge, to give a finish to the hinge.

In fig. 2, the sameletters refer to the same parts The holes for screwsin B are seen to be in the ordinary form, those in A, to be countersunkon both sides I of that leaf.

The leaf of the part A is seento be in the middle of the knob-H, so thatthis part of the hinge fits either right or left-hand jambs of doors.

The leaf of the part B is seen to be connected with its hinge by acurved portion, I, and the hinge has the axis or rod G in it.

r In fig. '3, the same facts are seen, and attention is called to thegreater prominence or clearness of thearrangement for reversing thispart, so as to fit either right or left-hand edge of doors, and gates,and other objects, by the lines E and E", cavities G. l

- The projections H are also clearly seen for the cav-v ity in the knobH, fig. 1.

The web D gives strength to the hinge.

The uses of the various partsof my hinge, and its I advantages, areclearly apparent to those skilled in the art to which it appertains. p

I am aware of the existence of a similar device in hingesas shown inmine; but

What I claim, is-

The combination of the CALVIN ooLE.
